Hi there, Beast here in Hemet Ca I am considering to move my wall heater from the hallway into the basement where I can easily vent the hot exhaust gasses under my house in the crawl space and heat my oak wood floors with the exhaust heat that is currently allowed to exit a straight up and out pipe. I want fresh air in and to exhaust air that is lowest in the basement for the reason of radon and heavier gases like carbon dioxide and small amounts of carbon monoxide. These are pushed out first under the house then into the attic for fullest heat recapture. The heaters hot plate is confined to a vent where air is drawn into it from the return cooler air drains to hallway under door, the fan blower send the heated air up over to cieling vents and into the heating areas by ducts. It seems such a loss of heat to me, up out the roof without heating any space, the crawlspace is a good place to heat with wooden floors, the exit from their being up and into the attic fro final dispersal exit out attic venting.The basement is unused space and heating it would not be needed, therefore a closed vent to the ducts of the heat source is good and their is a supply of fresh air added to both. I would rather use individual room gas heaters that are ventless types and get over 99% energy use. I understand CA relented as one of three states that banned these but have not heard any regulations on them provided and am not sure. I cant order them from CA though I am sure I could have my brother in law in MI send me one or so I buy through him.
Does anyone know if their are any current regulations and standards set on ventless gas space and water heaters in southern califorina which were approved to be used in CA in 2008?
